超链接可以在WPF控件中显示的XPS文件中工作吗？

I'm trying to create a help system for a software application. The interface is written in WPF. I have an XPS file (produced from a Word doc) that I want to access from the application. The XPS file contains hyperlinks that redirect within the XPS file. I can display the file using the DocumentViewer control, but the hyperlinks don't work. (When I view the same XPS file in the XPS Viewer, the hyperlinks work.) I'm new to WPF, so I may be overlooking something, but I've been trying to make this work for a week now and though I'm learning along the way I'm not getting anywhere with the task at hand. I'd greatly appreciate any help. -DaveI'm trying to create a help system for a softwa
